The objective of this paper is two-folded. The former is to report the experience of the deployment of cooperative proxy server on TANet. The latter is the survey of current state-of-the-art cooperative proxy server that was purposed in the literature or proprietary product. We study deep into the architecture of each scheme. Then, we make the comparison of these alternatives. From the analysis, it sounds that no one can advantage over others completely. It depends on what your requirement is. This reveals that although theoretically no problem but it never guarantees to work well in certain network environment.
